IMPROVEMENT IN HORSE-POWERS.'

. Specification forming part of Letters Patent No. 56,362, dated July17, 1866.

To all whom 'it may concern:

Be it known that we, H. L. BUGKWALTER and J. A. BUOKWALTER, ofKimberton, in the county of Chester and State of Pennsylvania, haveinvented a new and useful lmprovement in Horse-Powers; and wedo herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specificat-ion, in which- Figure l is an elevation of a verticallongitudinal section through the frame of the machine taken on the linea' of Fig. 2. Fig. 2 is an end view. Figs. 3 and 4 are detailed views ofthe coui'iter-shafts D and h.

The object ofthis invention is to simplify the construction ofhorse-powers, and increase their usefulness and lessen their cost, bycombining in the same wheel the gear-wheel, by which motion is impartedto the belt-wheel, and the sprocket-pulley, which receives the chain;also, by providing two counter-shafts with pinions, one running on theinner circumference and the other on the outer circumference of thecog-wheels, to either of which the belt-wheel may be connected. When itis connected to the counter-shaft D its motion is in a directioncontrary to the motion of the cog-wheels, and when it is connected tothe counter-shaft hits motion is in the same direction with them. Bythis meansthe direction of motion of the belt-wheel is reversed and thespeed is varied.

A designates the frame of the machine. B B are com bined cog andsprocket wheels, mounted on a shaft, E, that runs in bearings in thesides of the frame.

Instead of having the cog wheels and sprocket wheels or pulleysseparate, and driving the former by means of intermediate gearing, wehave combined the sprocket and cog wheels in one wheel, vformed and madein one casting, that part of the wheels which carries the sprockets Obeing on the inner side, and the other part being provided with cogsboth 011 the inner and outer circumference of the rim. lThe spokes orarms of the wheels are set within that part of the rim which carries thesprockets, so as to give room for the pinion i of the counter-shaft D towork. The counter-shaft D is set in front of the cogwheels B, and lowenough to clear the chain that engages the sprockets. It has twopinions, it', which are engaged by the cog on the peripheries of thewheels B.

F is a belt-wheel, which is connected to the end g of the counter shaftD by means of a screw, J. rlhe counter shaft D is placed within one ofthe cog-wheels B, its pinion t' engaging' with the cogs formed on itsinner circumference, as seen in Fig. 1. rIlle outer end of this shaft Dprojects as far as the end of the shaft D, and is formed, like thatshaft, to fit the hub of the belt-wheel.

It will be observed from this construction that when it is desired toreverse the motion of the belt-wheel it is to be changed from onecountershaft to the other, and also that, since the pinions of thecounter-shaft D are engaged.

by the cogs formed on the peripheries of the wheels B, it will, when thebelt-wheel is connected with it, drive the belt-Wheel at a higher speedthan when said belt-wheel is connected to the counter-shaft D', for thereason that the latter shaft is nearer the center of motion of thedriving-wheels B-that is, to the shaft E. In this Way an easy mode ofreversing the motion of the belt-wheel is placed within the reach of theoperator by merely changing it from one counter-shaft to another.

We claim as new and desire to secure by Letters Patenty 1. In theconstruction of horse-powers, the combination,- in 011e wheel, of thesprockets which engage the shafts of the chain and the cogs whichcommunicate motion to the counter-shaft, substantially as described.

2. ln horse-powers, placing two counter shafts in gear with thecog-wheels of the machine, one within and one without their rims, incombination with the belt-wheel, the same being so made and arrangedthat the beltwheel may be changed from one to the other at the pleasureof the operator, substantially as described.
